I generally don't tweak my puzzles after the first draft, but this time I tried to accomodate some of the CtC testers feedback and see how much I can improve it. There were remarks about a cryptic and unintuitive step, and it took three iterations to make the puzzle smooth enough while keeping most of the interesting logic intact. I should learn to do this with my puzzles more often.
